ABSTRACT:
A device for coupling a cassette tape recorder to a microcomputer comprises several series-connected elements, such as a pulse shaper, a delay element, a flip-flop, a commutator whose another input is connected to an output of the pulse shaper, a reversible counter, and a shift register. The device, according to the invention, also comprises a counter whose one input is a clock input of the device, another input is connected to an output of the delay element, while an output is connected to a second input of the flip-flop, and a timer whose inputs are connected to the clock input of the device, to an output of the commutator, and to an output of the reversible counter and to a shift input of the shift register, respectively.
